A remote control is a device used to operate electronic equipment from a distance, typically without the need for physical contact. It sends signals to the device, allowing users to change channels, adjust volume, or power the device on and off. Commonly used with televisions, DVD players, and sound systems, remote controls enhance convenience and accessibility. Most remote controls use infrared (IR) technology, which transmits signals through light waves. Some modern remotes also utilize radio frequency (RF) or Bluetooth, enabling them to work without a direct line of sight. Devices like smart TVs and streaming boxes often come with advanced remotes that include additional features, such as voice control and touchpads.
